aTides - unsupported

PLEASE NOTE: Due to the failure of the in-app advertisment model to produce any income whatsoever for the last 10 years I regret to announce that no further updates will be made to this version. This app will remain free of cost but since my time is precious only the paid version of aTides will be receiving support and updates from now on. The paid version can be found here https://play.google.com/store/apps/details?id=net.sourceforge.atideslgcy

In addition, the 'Non-Free' region which contained ports for Canada and some areas of the UK, Germany and Holland not found in the Europe region is now defunct - as of 2020 there is no data for many of these ports, please do not ask for it.

aTides is a completely off-line worldwide tide prediction application using NOAA/XTide harmonic data files.

It is based on code from uTides which in turn is based on xTides. If you are familiar with how xTides works you will be familiar with aTides. aTides however only contains a subset of features from xTides. Some data may be out of date and not all ports are available, please do not ask for more ports unless you can provide the harmonics file.


If you use this app, please consider contributing to the developer's beer fund, the ad-free version is only a fraction of the cost of a pint of beer!

If you want to see this app survive and don't want to buy the Ad-Free version please visit one of the sponsors ads every time you use it. No clicks = no revenue = a dead app. The Ad-Free version also receives all the latest bug-fixes and features first.
